Point-to-Point Communication with a Pair of UCW232C’s 

 

The UCW232C can be configured to communicate in pairs between two serial ports, also called point-to-

point communication.   

 

 

 

                     

                                                                         

    

 

 

 

We need to setup one adapter as a server in Simple AP mode (which it is by default) and one as a client 
in Station mode.  

Configuring the Server.

 

There is nothing to configure on the server. All default parameter values can be used.  

 
Configuring the Client.

 

Connect the other UCW232C to your computer’s access point over WiFi; we will configure this adapter 
as the client. Login to the admin page by using a web browser (use Firefox).  

Go to the “Wi-Fi” menu and select “Station” from the “Wi-Fi Mode” setting. 

Turn on the 

server 

adapter. 

 

 

 

 

 

 

Server in Simple AP mode (Default)

 

Client in Infrastructure/Station mode
